Historical review

Den Heyer (1977a) erected Neoscirula for three African cunaxids, Neoscirula theroni, Neoscirula natalensis, and Neoscirula sevidi. Shiba (1978) described the first Neoscirula outside of Africa, Coleoscirus ogawai. Den Heyer (1978b) erected the subfamily Coleoscirinae, tribus Neoscirulini and assigned Neoscirula to it. Den Heyer (1980b) described another African Neoscirula, Neoscirula delareyi. Neoscirula vitulus was described from Ukraine by Barilo (1991). Smiley (1992) transferred Neoscirula from Coleoscirinae to Bonziinae as he thought setae g1 were geniculate; he also described Neoscirula luxtoni, Neoscirula proctorae, Neoscirula kenworthyi, moved Neoscirula ogawai from Coleoscirus, and provided a key to known world species. Neoscirula abraensis, Neoscirula aspirasi, Neoscirula imperata, Neoscirula makilingica, Neoscirula puntiglupa were described by Corpuz-Raros (1996e) from the Philippines. Lin and Zhang (1998) described Neoscirula miaofengensis and Neoscirula bidens. Neoscirula saitoi was described by Lin and Zhang (2002). Corpuz-Raros (2007) described two more Philippine Neoscirula: Neoscirula laboensis, Neoscirula taclobanensis. Mejia-Recamier and Palacios-Vargas (2007) described Neoscirula aliciae, Neoscirula baloghi, and Neoscirula hoffmannae. Den Heyer and Castro (2008c) described Neoscirula flechtmanni, Neoscirula oliveirai, and Neoscirula queirozi. Skvarla, Fisher, and Dowling (2011) described Neoscirula reticulata. Den Heyer (2011c) described Neoscirula sepasgosariani.

Diagnosis

Gnathosoma. Pedipalps 5-segmented and end in a strong claw, which is complemented with a tooth in some species; they extend to the tip of the hypognathum or slightly beyond. Basifemur and telofemur are fused but retain the suture; each has a dorsolateral simple or spine-like seta. Pedipalp tibiotarsus short and cone-like. Subcapitulum with 4 pairs of setae (hg1–4). Seta hg1 longest and in some species bent at 90 degrees, though not geniculate as in Bonziinae. Adoral setae present or absent. Chelicera with seta present or absent.
Idiosoma, dorsal. Proterosomal shield weakly sclerotized and ill-defined, granulated or papillated; some species possess subcuticular reticulations.
Idiosoma, ventral. Coxae I–II separate or fused medially into a single sternal shield. Coxae III–IV contiguous on either side, restricted to area around trochantral bases. Dorsal cupules im present laterad to e1; ventral cupules ih present near h2, anal plates. Legs shorter than body. Tarsi never constricted apically so as to end in lobes. Apices of solenidia cylindrical, not swollen as in Coleoscirus and Scutascirus. Trichobothrium on leg tibia IV present. Ambulacral claws smooth and occur on either side of a 4-rayed empodium.

Neoscirula hoffmannae Mejia-Recamier & Palacios-Vargas, 2007 is excluded from the following key as it is only known from the male.
